Abstract
The utility model relates to an engine air cylinder cover jacket, which comprises a main water inlet, an auxiliary water inlet and a main water outlet, wherein the main water inlet is arranged on an exhaust side of an air cylinder cover, the auxiliary water inlet and the main water outlet are arranged on an air inlet side, and cooling liquid flow channels are arranged between the main water inlet, the auxiliary water inlet and the main water outlet and arranged on the periphery of air outlet channels, air inlet channels and spark plugs. The engine air cylinder cover jacket enables the air cylinder cover to be reasonably and fully cooled, enables temperature fields to be uniformly distributed, and prevents local thermal stress from being overlarge, thereby improving strength and reliability of the air cylinder cover and related parts.
Description
Technical field
The utility model belongs to technical field of automobile engine, specifically refers to a kind of water jacket of engine cylinder cover.
Background technique
Cylinder cap is as the key components and parts of motor, work long hours under the mal-condition of high temperature, high pressure, high wearing and tearing and deep-etching, heat load and mechanical load are all very high, and the performance quality of its cooling system directly affects intensity and the reliability of cylinder head and related components thereof.Therefore require when cylinder head in design to cylinder head carry out rationally, cooling fully, make uniform temperature fields distribute as far as possible, prevent because of cylinder head excess Temperature or the excessive phenomenon of the even generation localized heat of temperature distributing disproportionation stress.
Cylinder head water jacket in the past generally only has a water intake and a water outlet, and is arranged in cylinder cap rear and front end.Due to the restriction of intake-outlet, flowing of cooling liquid is slower, and very easily occurs that current are detained.Water intake is arranged in one end of motor in addition, and this just causes the other end cooling effect of motor poor.Because special coolant flow passage is not arranged in cylinder head exhaust side ridge area, cause the cooling effect of cylinder head exhaust side poor.
Model utility content
The purpose of this utility model is the defect existing for prior art, cooling bad while providing a kind of water jacket of engine cylinder cover of new structure, the technical program can solve engine cylinder cover to work long hours, the problem that local temperature is too high.
The utility model is achieved through the following technical solutions:
A kind of water jacket of engine cylinder cover, comprises water main inlet port, auxiliary water intake and main water outlet;
Described water main inlet port is positioned at the exhaust side of cylinder head, and auxiliary water intake is positioned at air inlet side, and main water outlet is positioned at air inlet side;
The described passage that has predetermined volume between water main inlet port, auxiliary water intake and main water outlet is the passage of cooling liquid circulation;
All there is the flow channel of cooling liquid in the surrounding of each air outlet flue, intake duct and spark plug.
Described each cylinder have a water main inlet port and an auxiliary water intake on the position of corresponding cylinder head, on whole cylinder cap, have a main water outlet.
Described auxiliary water intake is positioned on the passage that the cooling liquid of air outlet flue sidewall and intake duct sidewall collects to main water outlet.
The flow channel that described each water main inlet port connects cylinder cap is three, is respectively two flow channels flowing along air outlet flue sidewall and the flow channel along the ridge area in the middle of two air outlet flue sidewalls.
The flow channel of the intake duct sidewall that the flow channel in auxiliary water intake connection cylinder head is connected with water main inlet port is communicated with.
Useful technique effect of the present utility model is:
The technical program can make cylinder head obtain rationally, cooling fully, uniform temperature fields is distributed, prevent, because of cylinder head excess Temperature or the excessive phenomenon of the even generation localized heat of temperature distributing disproportionation stress, to have strengthened intensity and the reliability of cylinder head and related components thereof.

Embodiment
Describe the technical solution of the utility model by specific embodiment below, following instance is only exemplary, only can be used for explaining and explanation the technical solution of the utility model, and can not to be interpreted as is the restriction to technical solutions of the utility model.
Embodiment 1 as depicted in figs. 1 and 2, in the present embodiment, employing be four-cylinder setting, in other embodiments, cylinder number changes as required.Water main inlet port 1 is positioned at the exhaust side of cylinder head, and auxiliary water intake 2 is positioned at air inlet side, and main water outlet 3 is positioned at air inlet side.In other embodiment of the present utility model, water main inlet port 1 is positioned at the air inlet side of cylinder head, and auxiliary water intake 2 is positioned at intake and exhaust side, and main water outlet 3 is positioned at exhaust side; But the exhaust side that is preferably water main inlet port 1 and is positioned at cylinder head, auxiliary water intake 2 is positioned at air inlet side, and main water outlet 3 is positioned at air inlet side.
In each cylinder head, there are a water main inlet port 1 and an auxiliary water intake 2, on whole cylinder cap, have a main water outlet 3, in the present embodiment, have four water main inlet ports, four auxiliary water intakes and a main water outlet.Wherein, each water main inlet port is positioned at the neutral position of two air outlet flue front panels; Each auxiliary water intake is positioned on the passage that the cooling liquid of air outlet flue sidewall and intake duct sidewall collects to main water outlet; Main water outlet is positioned at the neutral position of four-cylinder air inlet side.
Between water main inlet port, auxiliary water intake and main water outlet, have the passage of predetermined volume, for the passage of cooling liquid circulation, be also referred to as water jacket, cooling liquid flows by them.All there is the flow channel of cooling liquid in the surrounding of each air outlet flue, intake duct and spark plug.Each water main inlet port 1 forms three independent streams after entering cylinder cap, is respectively the 3rd stream 8 flowing in the first stream 6 of flowing along air outlet flue 4 sidewalls and the second stream 7 and the ridge area 5 in the middle of two air outlet flue sidewalls; Cooling liquid is discharged from main water outlet after collecting along the both sides stream of intake duct sidewall after three flow path; The cooling liquid entering from auxiliary water intake and the cooling liquid entering from water main inlet port flow into main water outlet intake duct sidewall collects, for the intake duct of cooling segment.Between exhaust side and air inlet side, form the crossing current of cooling liquid, the ridge area of effective cooling cylinder cap.
In the technical program, cylinder head can obtain rationally, cooling fully, uniform temperature fields is distributed, prevent, because of cylinder head excess Temperature or the excessive phenomenon of the even generation localized heat of temperature distributing disproportionation stress, to have strengthened intensity and the reliability of cylinder head and related components thereof.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that not departing from principle of the present utility model and spirit and can carry out multiple variation, amendment, replacement and modification to these embodiments, scope of the present utility model is by claims and be equal to and limit.
